    AViTA Pulse Oximeter (SP62B)

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    The Fingertip Pulse Oximeter are intended for measuring function of atterial hemoglobin (SpO2) and pulse rate for adults as non-invasive spot checking in professional caring environment. It is designed for fingers between 0.8cm and 2.3cm (0.3 inches to 0.9 inches) and for patients during no-motion condition. The device is prescription only.

    Device Description

    The subject device AVITA Pulse Oximeter with Bluetooth is non-invasive spot checking, not provided sterile, multi-use device, which can measure and display user's oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR) through finger during no-motion condition. The subject device is not for lifesustaining, not for implant and does not contain drug or biological products. The device is for prescription use. The subject device consists of sensor, electronic circuits, display and plastic enclosures. It is a battery powered device and is adopted with two color OLED screen to display SpO2 and PR. It is software-driven and does not include alarms.

    AI/ML Overview

    The provided text is a 510(k) Summary for the AViTA Pulse Oximeter (SP62B). It addresses medical device regulation, but it does not describe acceptance criteria and a study that proves the device meets specific acceptance criteria in the manner requested (e.g., in the context of an AI/ML algorithm's performance).

    Instead, the document details the equivalence of the new device to a predicate device based on various non-clinical performance and safety tests, and a clinical validation of SpO2 performance.

    Therefore, I cannot fully answer your request based on the provided text because the information specifically about "acceptance criteria and a study that proves the device meets the acceptance criteria" for an AI/ML device's performance, including details like sample size for test sets, data provenance, expert ground truth establishment, adjudication, MRMC studies, or standalone algorithm performance, is not present.

    The document mentions "acceptance criteria" generally for biocompatibility tests, electrical safety, and EMC testing, but not for an AI/ML performance study as implied by your detailed questions.

    Here's what can be extracted and inferred from the text regarding the device's overall performance validation, with limitations noted:

    1. A table of acceptance criteria and the reported device performance:

    The document states performance specifications rather than explicit acceptance criteria in a table format for each test, but the overall statement is that the device "met the acceptance criteria" for various tests. For SpO2 accuracy, the performance is explicitly stated.

    Test/ParameterAcceptance Criteria (Implied/General)Reported Device Performance
    SpO2 Accuracy (70-100% range)Within acceptable limits per ISO 80601-2-61 (likely ±2% or similar based on predicate)ARMS (Accuracy Root Mean Square) = 1.89%
    Electrical Safety & EMCCompliance with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, and ISO 80601-2-61Complied with all listed standards
    BiocompatibilityCompliance with ISO 10993-1, -5, -10, -23 and FDA Biocompatibility guidanceAll tested standards met the acceptance criteria
    Software V&VCompliance with FDA Guidance for "Moderate" level of concern softwareDemonstrates functional performance and compliance
    Cleaning ValidationDevice performance not affected after multiple cleaning proceduresPerformance not affected as illustrated in user manual

    2. Sample size used for the test set and the data provenance:

    • Test set sample size: For the clinical performance testing, it mentions "healthy, adult volunteers." The exact number (sample size) is not specified in the provided text.
    • Data provenance: "healthy, adult volunteers." The country of origin is not specified. The study was prospective as it involved clinical validation testing.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

    • This information is not applicable in the context of a pulse oximeter's SpO2 accuracy against a reference measurement. Pulse oximeters are typically validated against arterial blood gas (ABG) measurements (co-oximetry) in a controlled desaturation study, where the ABG is the direct, objective ground truth. Expert readers are not usually involved in establishing ground truth for SpO2 values.
    • The document implies the adherence to ISO 80601-2-61 for clinical performance, which outlines the methodology for such studies.

    4. Adjudication method for the test set:

    • Not applicable/Not specified. For SpO2 accuracy, the "ground truth" is typically the co-oximeter measurement from arterial blood, not a subjective interpretation requiring adjudication.

    5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

    • No. This is not an AI/ML device for diagnostic image interpretation. It is a pulse oximeter measuring physiological parameters.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

    • Not applicable in the AI/ML sense. The device itself is "standalone" in that it directly measures SpO2 and PR; it's not an AI algorithm assisting a human interpreter.

    7. The type of ground truth used:

    • For SpO2 accuracy, the ground truth is implied to be co-oximetry measurement from arterial blood gas (ABG), as is standard for pulse oximeter validation according to ISO 80601-2-61. The document states "Clinical performance was conducted per ISO 80601-2-61. The clinical validation testing of the SpO2 performance under no motion on healthy, adult volunteers in the range of 70% to 100%."

    8. The sample size for the training set:

    • Not applicable. This is not an AI/ML device that requires a "training set" in the machine learning sense.

    9. How the ground truth for the training set was established:

    • Not applicable. (See point 8)
